In June, Lovato, 24, commented on a meme of Carey, 46, and Ariana Grande that Carey is “a legend and so talented but constantly disses people. It’s nasty the way she treats Jennifer [Lopez]. Ari did nothing wrong.”

“I don’t know her either and so I wouldn’t say anything to her,” Carey sassed. “She should come up, introduce herself to me, say, ‘Here’s my opinion, what do you think about it?’ That’s how you handle s–t, OK?”

As for whether Carey knew Grande, 23, she diplomatically replied, “No. I don’t know … Honestly, I’m not familiar. I listen to hip-hop more than I listen to pop music.”
